RS232 <> 20mA interface, Industry

  • RS232 <> 20mA interface, Industry

Serial interface - connect with galvanic isolation

The Interface connects devices equipped with an RS232 interface to active or passive 20mA components. The built-in galvanic isolation ensures uninterrupted transmission in industrial environments.

Properties

Interfaces:

  • 1 x RS232
    • 9-pin Sub-D plug with PC pin assignments
  • 1x 20mA
    • 9-pin Sub-D plug
    • Alternate designations: Current loop, TTY, line current interface
  • Galvanic isolation between the ports
    • Isolation voltage 1kV DC

Management and Connectivity:

  • Active/Passive mode can be set individually for both loops
  • No re-configuration of transmission parameters required

Power supply:

  • External
    • 12V-24V AC/DC via plug-in screw terminal
    • Galvanically isolated power connection

Standards & more

  • Conforms to standards both in office and industrial environments:
